Shopify does not recongnize Subscriptions

[arturogo]

Hello, I installed the Appstle Subscriptions app and everything seems fine during the customer's purchase, however, after the purchase, the Appstle app does not show any subscriptions. I asked the Appstle support team for help and they told me that the reason is because Shopify does not recognize the purchase as a subscription. I'm using Narrative theme, and this is my product https://cervezarefran.com/collections/cervezas/products/copia-pack-varias?variant=45059683352740&sel...

Any idea what is happening or if I missing something?

Thank.s
